AI Technical Summary

Benefits of technology

The solution effectively decodes only necessary FEC blocks, saving power and allowing mobile stations to handle bursts beyond their decoding capacity by selectively decoding only the required data, thus enhancing system operation freedom and reducing power consumption.

Problems solved by technology

As a result, power consumption is increased in the MS.

Abstract

A decoding apparatus and method in a BWA communication system are provided, in which an ID-based decoder controller detects an ID from a data block by partially decoding the data block, and if the ID indicates that the data block is not for the receiver, outputs a control signal commanding non-decoding for the data block, a bitmap table controller indicates the data block as a non-decoding data block in a bitmap table according to the control signal, and a decoder distinguishes data blocks to be decoded from non-decoding data blocks based on the bitmap table, decodes the data blocks to be decoded and outputs the decoded data blocks, and simply outputs the non-decoding data blocks without decoding.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION[0001]This application claims the benefit under 35 U.S.C. §119(a) of a Korean Patent Application filed in the Korean Intellectual Property Office on Nov. 16, 2006 and assigned Serial No. 2006-0113107, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to control of a downlink channel decoder in an Institute of Electrical and Electronics Engineers (IEEE) 802.16e Broadband Wireless Access (BWA) communication system. More particularly, the present invention relates to an apparatus and method for avoiding decoding of unnecessary Forward Error Correction (FEC) blocks using Connection Identifier (CID) information in a Medium Access Control (MAC) header.[0004]2. Description of the Related Art[0005]An active study area for 4th Generation (4G) communication systems is the provisioning of services with diverse Quality of Service (QoS) requi...
